TFIIIC

TFIIIC is a protein complex that plays a crucial role in the process of gene expression, specifically in the transcription of certain small RNA genes. It acts as a scanner and organizer, recognizing specific DNA sequences associated with these genes. Once it binds to these regions, TFIIIC helps recruit another protein complex called RNA polymerase III, which is responsible for copying the gene's DNA into RNA. This RNA then participates in various cellular functions. Essentially, TFIIIC is a key facilitator ensuring that small RNA genes are properly identified and activated for transcription within the cell.
